A new clue to how multicellular life may have evolved

A new clue to how multicellular life may have evolved
2025-03-31
Life emerged on Earth some 3.8 billion years ago. The “primordial soup theory” proposes that chemicals floating in pools of water, in the presence of sunlight and electrical discharge, spontaneously formed organic molecules. These building blocks of life underwent chemical reactions, likely driven by RNA, eventually leading to the formation of single cells. But what sparked single cells to assemble into more complex, multicellular life forms? Nature Physics published a new insight about a possible driver of this key step in evolution — the fluid ...

ALL ALS consortium launches website to advance ALS research

2025-03-31
ALL ALS Consortium Launches Website to Advance ALS Research The Access for All in ALS (ALL ALS) Consortium announced the launch of its official website, creating a central hub for information about its initiatives and clinical research studies. ALL-ALS.org is designed to inform and engage researchers, clinicians, and current and prospective study participants. The ALL ALS Consortium formed in fall 2023 with funding from the National Institutes of Health (NIH). The consortium consists of 35 clinical sites in the United States and Puerto Rico, led by researchers at Barrow Neurological Institute in Phoenix, Arizona and Massachusetts ...

Many TB cases may have gone undetected in prisons in Europe and the Americas during COVID-19

2025-03-31
EMBARGOED UNTIL 6:30 P.M. EST on Monday, March 31, 2025 Contact: Jillian McKoy, jpmckoy@bu.edu  Michael Saunders, msaunder@bu.edu  ##  Many TB Cases May Have Gone Undetected in Prisons in Europe and the Americas During COVID-19 A new study found that reported diagnoses for tuberculosis were consistently lower than expected throughout the pandemic, even though incarceration rates remained largely consistent and TB detection among the general population managed to reverse after an early-pandemic decline.  Incarcerated populations have a high risk of developing tuberculosis ...

Predicting older people’s frailty helps doctors intervene earlier
2025-03-31
UNDER EMBARGO UNTIL 00.01 AM BST ON TUESDAY 1 APRIL The new Electronic Frailty Index 2 (eFI2) is now available to 60% of England’s GPs thanks to research funded by the National Institute of Health and Care Research (NIHR) and conducted by researchers at the University of Leeds and UCL  GP data on 36 health problems such as dementia, falls and fractures will help medical professionals to more accurately identify older people’s frailty and intervene earlier  Interventions may include a holistic assessment and treatment plan, falls prevention, targeted medicines review, and resistance exercise ...

New study validates lower limits of human heat tolerance

2025-03-31
A study from the University of Ottawa’s Human and Environmental Physiology Research Unit (HEPRU) has confirmed that the limits for human thermoregulation—our ability to maintain a stable body temperature in extreme heat—are lower than previously thought. This research, led by Dr. Robert D. Meade, former Senior Postdoctoral Fellow and Dr. Glen Kenny, Director of HEPRU and professor of physiology at uOttawa's Faculty of Health Sciences, highlights the urgent need to address the impacts of climate change on human health. The study found that many regions may soon experience heat and humidity levels that exceed the safe limits ...

UTA takes lead with mobile lab to address rural health care crisis

UTA takes lead with mobile lab to address rural health care crisis
2025-03-31
Texas has the most rural residents of any state, with nearly 3 million people spread across a vast landscape. If rural Texas were its own state, it would rank as the 36th most populous. Yet, rural Texans face significant barriers to health care that their urban counterparts do not. More than a quarter of the state’s 172 rural counties lack a hospital, and those with at least one hospital often struggle with a shortage of qualified health care personnel, such as nurses and first responders. To address these growing challenges, The University of Texas at Arlington introduced its new Mobile Simulation Lab on Friday. It’s the first in Texas dedicated ...

New flexible hydrogel could improve drug delivery for post-traumatic osteoarthritis treatment

2025-03-31
Post-traumatic osteoarthritis (PTOA) is a condition that affects joints after an injury. Current treatments focus on relieving symptoms but do not prevent or stop the progression of the condition. Although emerging therapies have shown promise in preclinical studies, a major obstacle is delivering these therapies effectively into the joint, a highly dynamic environment subjected to constant mechanical stress. Researchers at Mass General Brigham have created a new hydrogel to improve drug delivery for treating PTOA. The hydrogel, ...
